One of the three Macs we need to sync is still on Snow Leopard, so I can't test yet. And it appears it's all or nothing. I can't, for example, sync photos from my iPhone to my Mac without going whole hog. I need to migrate all info to iCloud. We'll do that, but as the one outlier Mac is at the college, I don't have much control. (There were rumors a while back that Snow Leopard would get an iCloud preference pane. But I haven't seen anything recent.)

Also, it's not exactly clear to me how PhotoStream works. I'd like to sync my iPhone with my iMac, maybe.* But I certainly don't want a month's worth of photos from Aperture uploaded. That'd be hundreds of photos in some months, almost all not things I would want to look at on my iPhone. So do I get the choice of it up as a one way sync?

I'll take a shot at your last question in a separate "Photo Stream" thread, since this thread was intended to be about the migration process from MobileMe to iCloud.
